Using the table below, what is the change in enthalpy for the following reaction when all reactants and products are in the gaseous state?
Carbon Monoxide + Oxygen Carbon Dioxide
Substance ΔHf (kJ/mol)
CO2 (g) -393.5
CO (g) -110.5
O2 (g) 0.0
O3 (g) 142.0
H2O (g) -241.8
H2O (l) -285.8
CH4 (g) -74.86


A. −283.0 kJ

B. −708.0 kJ

C. −566.0 kJ

D. 566.0 kJ

Answer 2

change in enthalpy formula is H= U+PV

Answer 3

i am thinking the first one is B what about yourself?

Answer 4

I was thinking between A and B so I like your answer

Answer 5

oh good

Answer 6

for the second one did you get c?

Answer 7
